NOTES  ON  CHIP  COMPONENT  REPLACEMENT
• 

Never reuse a disconnected chip component.

• 

Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.

SAFETY  CHECK-OUT
After correcting the original service problem, perform the follow-
ing safety check before releasing the set to the customer:
Check the antenna terminals, metal trim, “metallized” knobs, 
screws, and all other exposed metal parts for AC leakage.
Check leakage as described below.

LEAKAGE  TEST
The AC leakage from any exposed metal part to earth ground and 
from all exposed metal parts to any exposed metal part having a 
return to chassis, must not exceed 0.5 mA (500 microamperes.). 
Leakage current can be measured by any one of three methods.
1.  A commercial leakage tester, such as the Simpson 229 or RCA 

WT-540A. Follow the manufacturers’ instructions to use these 
instruments.

2.  A battery-operated AC milliammeter. The Data Precision 245 

digital multimeter is suitable for this job.

3.  Measuring the voltage drop across a resistor by means of a 

VOM or battery-operated AC voltmeter. The “limit” indication 
is 0.75 V, so analog meters must have an accurate low-voltage 
scale. The Simpson 250 and Sanwa SH-63Trd are examples 
of a passive VOM that is suitable. Nearly all battery operated 
digital multimeters that have a 2 V AC range are suitable. (See 
Fig. A)

CAUTION
Use of controls or adjustments or performance of procedures 
other than those specifi ed herein may result in hazardous radia-
tion exposure.

UNLEADED  SOLDER
Boards requiring use of unleaded solder are printed with the lead-
free mark (LF) indicating the solder contains no lead.
(Caution:  Some printed circuit boards may not come printed with 

the lead free mark due to their particular size)

Unleaded solder has the following characteristics.
•  Unleaded solder melts at a temperature about 40 °C higher 

than ordinary solder.

 

Ordinary soldering irons can be used but the iron tip has to be 
applied to the solder joint for a slightly longer time.

 

Soldering irons using a temperature regulator should be set to 
about 350 °C.
Caution: The printed pattern (copper foil) may peel away if 

the heated tip is applied for too long, so be careful!

• Strong 

viscosity

 

Unleaded solder is more viscous (sticky, less prone to fl ow) 
than ordinary solder so use caution not to let solder bridges 
occur such as on IC pins, etc.

• 

Usable with ordinary solder

 

It is best to use only unleaded solder but unleaded solder may 
also be added to ordinary solder.

The laser diode in the optical pick-up block may suffer electro-
static break-down because of the potential difference generated by 
the charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic break-down and also 
use the procedure in the printed matter which is included in the 
repair parts.
The fl exible board is easily damaged and should be handled with 
care.

NOTES  ON  LASER  DIODE  EMISSION  CHECK
The laser beam on this model is concentrated so as to be focused 
on the disc refl ective surface by the objective lens in the optical 
pickup block. Therefore, when checking the laser diode emission, 
observe from more than 30 cm away from the objective lens.

CHECKING  THE  OPERATION  AFTER  REPAIR
After repair completion, connect the “iPod” etc. corresponding to 
this unit, and check the operation of playback, charge, etc.

NOTE  OF  REPLACING  THE  TUNER  BOARD
When the TUNER board is defective, replace the complete mount-
ed board.

NOTE  OF  REPLACING  THE  DAB  BOARD
When the DAB board is defective, replace the complete mounted 
board.

NOTE  OF  REPLACING  THE  ANTENNA  BOARD
When the ANTENNA board is defective, replace the WIFI AN-
TENNA 2.4 GHz SVX (Ref No. ANT1).

NOTE  OF  REPLACING  THE  TOUCH  KEY  BOARD
When the TOUCH KEY board is defective, replace the REAR 
SVX PANEL (Ref No. RP1).

NOTE  OF  REPLACING  THE  POWER  KEY  BOARD
When the POWER KEY board is defective, replace the REAR 
SVX PANEL (Ref No. RP1).

NOTE  OF  REPLACING  THE  MS-091  BOARD
When the MS-091 board is defective, replace the LOADING 
ASSY (Ref. No. CDM1).

NOTE  OF  REPLACING  THE  IC202,  IC203,  IC502,  IC602,  
IC851  AND  IC907  ON  THE  MAIN  BOARD
IC202, IC203, IC502, IC602, IC851 and IC907 on the MAIN 
board cannot replace with single. When these parts are damaged, 
replace the complete mounted board.

NOTE  OF  REPLACING  THE  CN1505  ON  THE  JACK-
NET  BOARD
CN1505 on the JACK-NET board cannot replace with single. 
When this part is damaged, replace the complete mounted board.

TEST  DISCS
